Could this be carpal tunnel symptoms?

Pain and swelling in the palm of my thumb, pain in my wrist, pain in my forearm and bicep. Going on 5 days now. Have tried icing it and taking ibuprofen. Doesn’t bring much relief. My hand feels weak and tired like if it were to rest it by my side or in my lap, that sensation would go away, but doesn’t. Applying pressure to my wrist however does ease the pain a bit. So I’ve got my hand/wrist in a brace to alleviate the pain and reduce use of it.

Plan to mention it to the PT on site at work tomorrow for his opinion. Not sure if it’s just from over use or if I slept on it weird, but no direct injury that I can think of.
